We are implementing writeback in tableu. For this we implemented webservice to update back the database table for one single value. but our requirement is such that we need to update multiple values. Since webservice is not able to handle multiple values we are looking for a script which can post the values from tableau to webservice and webservice write to database and I need to get back the updated values for those writeback applied columns. I need any code like XML or JSON code will work.
